The Jefferson Tools JEFTRQWRHSET03 Micrometer Torque Wrench Set is designed for professionals who demand accuracy, reliability, and durability when tightening critical fasteners. Covering a wide torque range across 1/4", 3/8", and 1/2" square drives, this versatile set is suitable for everything from light assembly work to heavy automotive and mechanical tasks.
Each wrench features a micrometer-style torque adjustment mechanism, allowing fast and precise torque setting with excellent repeatability. The flip-reverse chrome vanadium steel ratchet heads provide smooth operation and enable both clockwise and anti-clockwise use, making the wrenches practical in confined or awkward spaces.
Clear, easy-to-read dual-scale markings in Nm, kg.m, and lb.ft eliminate the need for conversions, while the knurled aluminium handles offer enhanced grip, comfort, and control during prolonged use.
Manufactured and calibrated in accordance with BS EN ISO 6789-1:2017, each torque wrench is individually tested to ±4% accuracy and supplied with its own numbered calibration certificate, ensuring confidence, traceability, and compliance in professional environments.
